Subject: [patch] qla4xxx: initialize some variables for gcc

Gcc complains because these variables aren't initialized.

drivers/scsi/qla4xxx/ql4_nx.c: In function ‘qla4_8xxx_get_flash_info’:
drivers/scsi/qla4xxx/ql4_nx.c:1952: warning: ‘fid’ may be used uninitialized in this function
drivers/scsi/qla4xxx/ql4_nx.c:1952: note: ‘fid’ was declared here
drivers/scsi/qla4xxx/ql4_nx.c:1952: warning: ‘mid’ may be used uninitialized in this function
drivers/scsi/qla4xxx/ql4_nx.c:1952: note: ‘mid’ was declared here

It's not a big deal.  We only print the uninitialized value on error
paths when debugging is enabled.  Still it's nice to clean it up and to
stop gcc from grumbling.
